Solar light panel

March 8th, 2010

Solar energy is the cleanest and inexhaustible of all known energy sources. Solar energy is nothing but the light, heat and other radiation that is emitted from the sun. Solar radiation holds huge amounts of energy and is responsible for almost all the natural processes on earth.

Solar Light panels are completely free standing. Simply fit the light components collectively, press the spike into the ground or screw on to the wall mounting, it really is that simple! Power is provided by solar panels, located tactfully on the head of the lights.

During the day the lights charge up with free solar energy via the solar panels collecting power from both sunlight and daylight. The energy is stored in long-life NiCad batteries (supplied) integrated into the lamp body. Often, these lights are designed to turn on automatically at end of the day, providing an enhancing effect through-out the night, and then charge up again during the day. All weather design ensures that Solar Lights are not affected by unfavorable weather conditions ensuring years of pleasure.

Science behind the working of Solar Light Panels:

The system operates just like a bank account. Withdrawals from the battery to power the light, source must be compensated for by adequate deposits of energy from the solar panels. Provided that the system is designed so deposits exceed withdrawals on an average daily basis, the battery remains charged and light source is consistently powered.

Features of our Solar Light Panels:

1.Automatic sunset sensors operate light at evening.
2.Strong design ideal for year round outdoor use.
3.Solid state Light Emitting Diodes give 20,000 hrs life.
4.These are the very economical lighting system.
5.Sun is a direct source of energy for the solar panel.
6.The battery is recharged during the day by direct-current (DC) electricity produced by the solar panel.
7.The light source is powered by the battery each night.
8.The electronic controls are used between the battery, light source and solar panels to protect the battery from overcharge discharge, and to control the timing and operation of the light.

Why to opt Solar Lights:

•Solar Lights are the very economical. As the cost of energy is always on the rise, every person is looking for more affordable options. Solar light panels are not only affordable but can be operated from natural sunlight, which is available for free for you. The natural sunlight provides the power for solar lights to work. They do not require electricity or gas. As this power is generated without using any external energy source, your energy bills will be much lower. Solar lights are the most reasonably priced type of outdoor lighting that you can find anywhere.

•No trenching, no metering, no wiring.

•A most important consideration is that these lights will not use up other energy resources. As electrical power and gas power are not needed, using solar light means that you are going green and you are doing your part to make sure that these resources are not depleted.

•These lights will get just the right amount of power to make them completely effective. These lights are not overly bright or very dim light that is essentially useless, but are completely effective.

•Solar light panels are easy to install. You will not require to waste money hiring a professional to do it. You can have your lights suitably installed and in great working condition in no time at all.

•Solar lights also look great. There are several different styles available that it will be effortless to find the style best suited to your needs. Whether you are looking for something modest, stylish, to blend in with the natural environment or to give a bold contrast, there is one accessible for you.

As you can see, there are plenty of reasons why you should consider adding solar yard lights to your home. They are the best choice for outdoor lighting available today. Let’s try to get out of this ferocious treadmill of paying hard earned money to the companies for their electricity. Make use of solar light panels and reduce your bill…….

Facts:

1.NASA estimated that the Sun gives or irradiates the earth 174 Petawatts (Pw) of solar energy every day. Out of this roughly 30% of energy is reflected back to space, and another major share is absorbed by our atmosphere. Even if we get only 10% of this energy which is about 17.4 Pw per day, it is still more than the whole daily energy requirement worldwide. [#1]
2.Solar light panels help in deterring crime and by using these lights, you can augment the visibility of your place thus augmenting the safety of people who walks along the pathway while taking the benefit of reduced electric bills.[#4]
3.Do you know out of total solar radiation that falls on our solar panel how much energy does our Solar cell absorb? Sorry to say that our simple solar panel can absorb only about 14 % or less.
4.Solar energy is sustainable, clean and green energy.
5.The batteries incorporated on Solar Lights panels are recharged during the day. The battery used is so efficient that it can hold power all through the whole night which is usually for 12 hours.[#4]
6.Solar energy with the help of developing technologies play an important role in reducing greenhouse gasses and helps in stimulating the economy.
7.Solar Energy is measured in kilowatt-hour. 1 kilowatt = 1000 watts.
8.1-kilowatt home solar system consists of about 10-12 solar panels and requires about 100 square feet of installation area. [#2]
9.Solar thermal technology can also create electricity by creating steam to power generators.
10.In 1990, a solar powered airplane flew across the U.S.[#2]

11.The “solar panel” accounts for between 40-50% of the total cost of an installed solar energy system. [#2]

12.During the 15th century, Leonardo da Vinci already had plans for solar concentrators in his notebooks.
13.In just one hour, the earth receives more energy from the sun than the entire world uses during a whole year.[#3]

14.Solar energy can produce lighting for indoor or outdoor use. It can be used to heat swimming pools, power cars, and small appliances. You can even cook food with solar energy.
15.According to a global price survey, solar energy prices have declined an average of 4% per year for the past 10 to 15 years.

Solar Attic Fan

March 4th, 2010

The Solar Attic Fan is an inexpensive way to use solar energy in your life, which helps to exhaust hot air from your attic. Powered wholly by free solar energy, this sleek and competent vent is both compact and quiet. Installed on a rooftop or in an end-wall or gable, solar attic fans operate each time there’s sunlight striking the solar module. Fully operational right from the box, it installs effortlessly, without electrical wiring, no expensive electrician and city permits. Most important feature is a single 10 watt unit can completely vent up to 1,200 square feet, operating at up to 850 cfms. Place it anywhere you need better circulation; attics, lofts, workshops, storage sheds, garages, even barns.

Solar Attic Fan provides attic venting which is an important aspect in maintaining a healthy energy efficient home. Proper venting cools your roof which not only extends the material life but also reduces the load on your air conditioning system. Attic venting also increases fresh air flow which reduces moisture build up produced by every day activities like showering and cooking.

Excess moisture trapped in your attic can cause many problems like rust and rot, increased bacteria and mold counts which can have a direct impact on your respiratory health. Solar attic fans simply change the grid energy source with free solar energy. They run when the sun is shining and adding heat to your house. They can be installed wherever unobstructed sunlight is available for their solar modules.

How Solar Attic Fan Work:

An electric fan to cool off an attic space is not a new concept. Many households use fans to drive out excess heat that builds up under the roof. These fans are typically connected to household AC power using thermostatic switch. The principle behind this is simple as air trapped under roof becomes very hot. By conduction, that heat passes into the rooms through their ceilings, resulting in increase of the temperature of the house. This in turn resulted in an increased use of air conditioning. By exhausting hot air from the attic space, attic fans trims down the need for air conditioning, saving money and energy in the process.

Benefits of Solar Attic Fan:

Lowers attic temperature:

Solar Attic Fans lowers attic temperature which results in reducing the load on the HVAC System. The most important reason for attic ventilation is to lower attic space temperature in the warmer months. Attic area can get very hot during summer days. Proper attic ventilation can help in reducing the temperature. Regardless of how much insulation is in the attic, heat can even then transfer into adjacent living spaces. Actually, extra insulation can add to temperature as heat is trapped in the insulation. Proper ventilation removes this excess heat build-up and hence helps in reducing the work load of the air conditioning system, thereby saving energy.

Prevents ice blocking in colder climates:

Heavy snowfall can generate ice wall that cause a roof to leak along the attic. Wintertime ventilation can help to avoid moisture build-up in the attic space which can dampen insulation, reducing its effectiveness, or contribute to mold growth, peeling paint or flaking plaster. Moreover, the heavy weight of the ice that fills the rain gutters can rip off the gutters. The best way to prevent this is through proper attic ventilation.

Extends the life of the roofing materials:

In the cooler months, moisture is the main concern. In spite of using vapor barriers to keep moisture from entering the attic, there are air leaks in the region of ceiling light fixtures, bathroom exhaust fans which allows unwanted moisture into the attic. Moisture condensing on the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing.

Attic ventilation evacuates the warm moist air that heat sources produce. Hot moist air enduring in the attic spaces can condense on the roof sheathing and rot it out and can also cause mold to build up on the interior walls.

Why to opt Solar Attic Fans:

• Because solar attic fans cost nothing to operate, and are more affordable to operate than conventional powered attic fans.
• By reducing attic temperature, attic fans helps to reduce summertime cooling loads at the same time provides ventilation without added utility load.
• Solar attic fans are easy to install and doesn’t have any wires hence eliminates the need for an electrician. You can easily install it using conventional materials, tools, and techniques
• Reduces cooling load on AC units
• Operates on free solar energy
• Adjustable solar panel

Facts:

  1. Retail prices range from about $350 to $600 depending on ventilation capacity, manufacturer, and optional features of the unit, such as a thermostat.[#1]
  2. Solar powered fans are fueled by the sun, so there is no cost of operation.
  3. Attic temperatures can get up to 150ºF without an attic fan.[#3]
  4. Attic solar fans can lower upstairs room temperatures by 10º.[#3]
    Attic solar fans help in lengthening roof life by keeping shingles cooler.
  5. Attic solar fans save up to 30% on air-conditioning costs.
  6. Attic solar fans are adaptable to any location, roof type, in any environment.
  7. You can even cook food with solar energy.
  8. Solar Energy is becoming more and more popular. The worldwide demand for Solar Energy is currently greater than supply.
  9. Solar energy can also be used to heat swimming pools, power cars, for calculators and other small appliances. It produces lighting for indoors or outdoors.

10. Solar energy is responsible for weather patterns and ocean currents. [#2]

11.  Clouds, pollution and wind can prevent the sun’s rays from reaching the earth.[#2]

12. Sunlight travels to the earth in approximately 8 minutes from 93,000,000 miles away, at 186,282 miles per second.[#2]

13. The sun is also the main source of non-renewable fossil fuels (coal, gas and petroleum), which began life as plants or animals     whose energy came from the sun millions of year ago. [#2]

Grid tied solar: Using Solar Power without Cutting Off Your Electricity

September 29th, 2009

With the upcoming increase in electricity rates and the green movement pushing alternative energy sources, the solar power industry has become a booming business. Many people are considering solar power as a way to break free of the conventions and whims of their electric company and be self sufficient when it comes to powering their home.

However, you don’t have to go completely off the grid to power your home with solar energy. In fact, most people who install a solar power system will stay tied to their electric company’s grid as a precautionary back up system. You see, when people go “off grid,” it means they cut all ties to their power company. They are no longer plugged into the power grid and rely solely on the power they generate through their solar panels. While the feeling of being self-sufficient is a great feeling to have, the people who do decide to go off grid completely are missing out on some exciting benefits that come with staying tied to your power company’s grid system.

Even though you install a solar power system on your house, it’s advantageous to stay connected to the grid for many reasons. One reason is simply the feeling of comfort you get from knowing that on the days where you may not generate enough power for your home, you still have the ability to draw power from your electric company. This keeps the power going no matter what it’s like outside. In times of stormy weather or days with less daylight, when your solar panels may not power up completely, you still can have electricity.

Staying tied to the grid can also give you the benefit of simply reducing your electric bill. If you can’t afford a total solar power system, there is the option of adding panels a little at a time as your budget allows. Even just a little bit of solar power to generate electricity for your appliances can make a significant dent in your electric bill. Some people only use solar power to generate electricity for the things they know pull the most power such as the central air conditioning unit.

Another advantage of staying tied to your power company’s grid system is the ability to generate electricity for the grid. If you are tied to the grid, and you generate excess electricity, that power doesn’t go to waste. It will feed back into the grid and your meter will roll backwards. This helps provide energy for your neighbors and also gives you some extra income at the end of the year. That’s right! The power company will pay you for any power your solar energy system provides to the grid. Each power company has their own rules and regulations on this, so check with them first on what their policy is concerning grid tied power. Watch the video below to learn more about the grid tie converter.

As we all know an increase in your electric bill is coming if it hasn’t already hit you. Electricity rates are jumping by at least 20 percent across the country, and you’ll see it hit hard in your electric bill once the rates have been established. Solar power tied to the grid can help offset these rate increases. Even if you only install a smaller solar power system, you can compensate for these rate increases with the amount of energy you produce with your solar panels.

And of course, another great benefit of solar power is being able to generate clean renewable power that is good for the environment. Even just a little solar power in your home can have a significant impact on the reduction of harmful toxins that are released into the atmosphere. Every little bit helps and by reducing the amount of power you use, you can do your part in the green movement.

Now that you know all of the benefits of grid tied solar power, you’re probably wondering how to get started. First, you need to decide just how much solar power you want to generate. Can you afford to power your entire house? Or do you want to just do a little at a time? Take a look at your last electric bill to get an idea of how many watts you use on a monthly basis. Then call your local utility company up to see what kind of programs or regulations they have about solar systems. Do they have a credit system? If so, then you may consider trying to install a complete solar power system on your home if it’s within your budget.

If you’re budget is low, under $1,000, then you will need to start out small. There are many do-it-yourself kits that you purchase online for about $200 that will allow you to set up your system by yourself. They usually come with one solar panel at a time, so you can gradually increase the amount of power you are generating as your budget allows. These can be frustrating thought if you don’t know what you’re doing. Make sure you do your research and if you are a technical person who can follow directions, you should be fine.

A good idea is to take the money that you are saving on your electric bill and start a fund for your next panel. Pretty soon, you’ll have enough to install several panels and increase your savings significantly.

you can check out that explain in more detail how to install these simple kits and even tie them together for more wattage output. Click on the video below to watch the first video of this series.

Solar power is the way of the future. With energy prices rising and the economy still underwater, becoming self sufficient and cutting your monthly bills is a necessity, and solar energy can give you the power to do just that. With just a little research, and a couple of phone calls to your local power company, you can begin providing your home with clean, renewable solar energy.
